Function Test

NOTE: Before testing, remove the left door panel, then

disconnect all connectors from the door panel.

10P CONNECTOR

DOOR PANEL

NOTE: Check the No. 4 (15A) fuse in the under-dash

fuse box before testing.

One or both inoperative:

1. Check for voltage between the YEL/BLK1 terminal

and body ground with the ignition switch ON (II).

There should be battery voltage.

If there is no voltage, check for an open in the

YEL/BLK1 wire.

If there is battery voltage, go to step 2.
2. Check for continuity between the BLK terminal and

body ground.

There should be continuity. If there is no continui-

ty, check for:

An open in the BLK wire.

Poor ground (G401, G402, G403).

Left inoperative:

Connect the YEL/BLK1 terminal to the YEL/RED terminal

and the YEL/WHT (or YEL/BLK2) terminal to body

ground with jumper wires.

The left mirror should tilt down (or swing left) when the

ignition switch is turned ON (II).

If the
mirror does
not
tilt
down
(or
does
not
swing

left), check for an open in the YEL/WHT (or

YEL/BLK2) wire between the left door mirror and the

switch.

If the wire is OK, check the mirror.

If the mirror doesn't move in either direction, repair

the YEL/RED wire.

If the mirror operates properly, check the mirror

switch.

Right inoperative:

Connect the YEL/BLK1 terminal to the BLU/GRN ter-

minal and the YEL/WHT (or BLU/BLK) terminal to the

body ground with jumper wires.

The
right
mirror should
tilt
down
(or
swing left) when

the ignition switch is turned ON (II).

If the
mirror does
not
tilt
down
(or
does
not
swing

left), remove the right door panel, and check for an

open in the YEL/WHT or BLU/BLK) wire between the

right door mirror and the switch.

If the wire is OK, check the right door mirror.

If the mirror doesn't move in either direction, repair

the BLU/GRN wire.

If the mirror operates properly, check the mirror

switch.ProCarManuals.com

Damaged Airbag or Tensioner Special Proce-

dure.

If an airbag or tensioner cannot be

deployed or triggered, it should not be treated as

normal scrap; it should still be considered a poten-

tially explosive device that can cause serious

injury.

1. If installed in a vehicle, follow the removal proce-

dures in this section.

2. Intertwine the stripped ends of the two airbag or ten-

sioner wires to make a short circuit.

3. Package the airbag or tensioner in exactly the same

packaging that the new replacement part came in.

4. Mark the outside of the box "DAMAGED AIRBAG

(or TENSIONER) NOT DEPLOYED" so it does not

get confused with your parts stock. If applicable,

also note on the box the VIN of the vehicle from

which it was removed.

5. Contact your Acura District Technical Manager for

how and where to return it for disposal.
Deployment Tool: Check Procedure.

1. Connect the yellow clips to both switch protector

handles on the tool; connect the tool to a battery.

2. Push the operation switch: green means the tool is

OK; red means the tool is faulty.

3. Disconnect the battery and the yellow clips.ProCarManuals.com
